If room temperature is 300K, is Gallium a solid, liquid, or gas?

Chemistry
1 answer:
disa [49]3 years ago
6 0

Answer:

Gallium is solid at 300K

Explanation:

X °C = 300 kelvin - 273.15 = 26.85 ° C

To know if Gallium is solid, liquid or gas; we should know the melting point of Gallium.

The melting point of gallium is 29.76 °C, which is 3 °C higher than the current temperature. This means it hasn't melted yet. So at 300 Kelvin, it is still solid. But the melting temperature is slightly above room temperature.

A food provides enough energy to raise the temperature of 2000 grams of water by 10°c. how many kilocalories does it contain?
Musya8 [376]

A food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.

1 Calorie is the amount of heat needed to elevate one gram of water to one degree Celsius temperature at one atmosphere of pressure.

The term "kilocalorie" is used to describe the amount of energy needed to increase 1 L of water's temperature by one degree Celsius at sea level.

Given

Mass of water (m) = 2000 g
Temp raise (ΔT) = 10°C

Heat capacity of water (C) =  1 calorie/g-C

Formula used

Heat (ΔH) = m × C × ΔT

                = 2000 × 10 = 20000 C

In Kilo calories

20000 C = 20000/1000 = 20 KCa

Hence, a food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.
